How to get the element type of List<T> from MonoObject*

[ffbh123456]

I have a MonoObject* that represents a List<T> from C#.
I need to retrieve the element type T — specifically, get a MonoClass* that represents the generic argument.
Is there an API that can help with this?
So far, I can get the MonoClass* of the object using mono_object_get_class(obj), but I haven’t found a clean way to extract the generic argument from there.

Thanks in advance!
